compression-comparison

A small tool to compare compression with Brotli and gzip.

The idea is to see how gzip and Brotli compare on your own data. To use it, replace input with an example of the data you'd want to compress, e.g. a JSON file with a response from your API. Then run

go run .

to see compression ratios, and

go test -bench .

to compare compression and decompression speed.

Brotli has a quality setting that lets you trade off speed and effectiveness. The benchmarks include quality 4, which should work well for on-the-fly encryption, and quality 11, which will give the best compression ratio.

Prerequisites

You'll need

• Go, of course.
• The Brotli library, including header files. On Ubuntu, sudo apt install libbrotli-dev should do the trick. On macOS, you can do brew install brotli.
